I fully acknowledge that hi vis and flashing lights make no difference if the driver chooses to drive above the speed limit, tailgates the vehicle in front, doesn't keep their windshield clean and free from obstructions, chooses to distract themselves with a phone, laptop, eating and drinking or passengers, takes drugs and or alcohol, doesn't maintain their vehicle correctly or exceeds it's safe limits, has no real understanding of the forces of nature i.e the distance it takes to stop a vehicle from 80mph, or the limit of road holding when steering hard, or the significant increase in stopping distance in snow and ice.
I also accept, and have previously argued the very fact that if we keep improving the visibility of people through lighting and clothing, then it becomes an arms race where those left behind become increasingly vulnerable, where as years ago they would have been perfectly safe. Human propensity for adaption is unfortunately a two edged sword, it often works for our benefit, but sometimes also to weaken us when we are lazy or shortsighted or greedy.
But it's hardly going to make road side workers any safer if they throw away their hi viz and wear black or camo. Hi viz is only one aspect of road safety such as proper education and training, enforcement and public campaigning,road and vehicle design. But if hi viz saves just one fatality, one family's grief, then it's worth every penny.

Where is the supporting evidence for such a claim? You simply don't know this for a fact. What does improve safety is focusing on who and what is doing the harm in the first instant, those who go about doing what they do with a blase, reckless and dangerous attitude towards their actions and how they see what they do in terms of presenting threat of harm as a non issue. Modifying that behaviour or removing them completely is proven to work, unlike hi-vis et al.
